descriptive output to stdout rather than returning it in an
allocated string as intended.</p></li>

<ul class="simple">

C99 vsnprintf() return values.</p></li>
<li><p>magick/draw.c, wand/drawing_wand.c (DrawAnnotation): Linux
glibc does not pass extended text characters if &quot;%.1024s&quot;
formatting convention is used.  Apparently it assumes that such
characters may be UTF8 and returns -1 rather than outputting the
string, even if it is assured to fit.</p></li>

tiff:lzmapreset=7</cite> for purposes of further experimentation.  Also

<li><p>magick/magic.c (StaticMagic): Be more specific when identifying
PNM subformats.  Return the specific subformat name PBM, PGM, or
PPM rather than PNM.  XV P7 format is now identified as &quot;P7 332&quot;.
Add detection of NetPBM PAM format.</p></li>

<li><p>magick/semaphore.c (DestroySemaphore): POSIX mutex statically
initialized via PTHREAD_MUTEX_INITIALIZER should not be destroyed.</p></li>
<li><p>configure.ac: DisableSlowOpenMP is now the default.  Use
--enable-openmp-slow to enable OpenMP for algorithms which
sometimes run slower rather than faster.</p></li>
